Blocks X and Y are attached to each other by a light rope and can slide along a horizontal, rough surfce. Block X gas a mass of 10kg and block Y a mass of 5kg. An applied force of 36N (right side) acts on block X. Suppose the magnitude of the force of friction on blocks X and Y and 8N and 4N respectively. The magnitude of tension in the string between the blocks is _______.
net force=36-8-4=24N
total mass=10+5 =15kg
acceleration of the system=24/15=1.6m/s2
for tension in the string
forces considered on mass 10kg
force applied-frictional force on X-tension=mass of X × acceleration
36-8-T=10×1.6
T=12N
